  1. CVE-2026-106583 7.8 Élevée

    OpenBSD OpenSSH

    In ssh in OpenSSH before 10.6, a $ or \ character can occur in a command-line username, leading to injection.

  2. CVE-2026-106589 2.9 Faible

    OpenBSD OpenSSH

    In sshd in OpenSSH through 10.6, in certain environments such as QNX 6 and SCO OpenServer 5, sshd-session can unexpectedly have root privileges. This is related to the GatewayPorts and StreamLocalForwarding configuration options, and lack of support for file-descriptor passing and unprivileged allocation of PTY devices.

  3. CVE-2026-106588 3.1 Faible

    OpenBSD OpenSSH

    In sshd in OpenSSH through 10.6, use of the macOS 27 (or later) SDK has the side effect of loss of sandboxing, which is potentially unexpected.

  4. CVE-2026-106587 3.3 Faible

    OpenBSD OpenSSH

    In sshd in OpenSSH before 10.6, the value "none" for a configuration option is sometimes interpreted as a filename but was intended to mean that a feature is disabled.

  5. CVE-2026-106586 4.3 Moyenne

    OpenBSD OpenSSH

    In sshd in OpenSSH before 10.6, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not, a different vulnerability than CVE-2026-73283.

  6. CVE-2026-106585 6.5 Moyenne

    OpenBSD OpenSSH

    In sshd and ssh in OpenSSH before 10.6, there is no check for whether the maximum packet length is exceeded during decompression of highly compressed data.

  7. CVE-2026-106584 3.3 Faible

    OpenBSD OpenSSH

    In ssh-keygen in OpenSSH before 10.6, certificates could have incorrect expiration times because of Daylight Saving mishandling. There can be a slightly more severe effect on users in certain Antarctic locations.

  8. CVE-2026-106582 3.7 Faible

    OpenBSD OpenSSH

    In sshd and ssh in OpenSSH before 10.6, an LZ77 dictionary coder can be used even though this is contraindicated by the arXiv 2609.07709 "Crossing the Streams" findings.

  9. CVE-2026-106555 7.5 Élevée

    OpenBSD OpenSSH

    In sshd in OpenSSH before 10.6, GSSAPIAuthentication authentication state can incorrectly be persisted across authentication attempts.

  10. CVE-2026-106553 7.5 Élevée

    OpenBSD OpenSSH

    In sshd in OpenSSH before 10.6, credentials can incorrectly persist after failure of a GSSAPIAuthentication authentication attempt.

  11. CVE-2026-106552 6.5 Moyenne

    OpenBSD OpenSSH

    In sftp in OpenSSH before 10.6, a server can trigger directory traversal (causing files to be written to unintended locations) during a recursive copy operation.

  12. CVE-2026-73283 2.5 Faible

    OpenBSD OpenSSH

    In sshd in OpenSSH before 10.5, the restrict keyword (in authorized_keys) was supposed to be applicable to tunnel forwarding but was not.

  13. CVE-2026-73282 4.8 Moyenne

    OpenBSD OpenSSH

    In ssh in OpenSSH before 10.5, a use-after-free for realloc data can occur if a certain pair of remote-forwarding operations are concurrent.

  14. CVE-2026-73281 3.5 Faible

    OpenBSD OpenSSH

    In ssh-agent in OpenSSH before 10.5, some operations can occur remotely but were intended to occur only locally, including operations that add tokens or use keys. This is caused by misinteraction between agent locking and the session-bind@openssh.com extension.

  15. CVE-2026-60002 9.4 Critique

    OpenBSD OpenSSH

    ssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re-exchange. (This outcome occurs only on the client side.)

  16. CVE-2026-60001 6.5 Moyenne

    OpenBSD OpenSSH

    sshd in OpenSSH before 10.4 does not always honor the minimum authentication delay.

  17. CVE-2026-60000 7.5 Élevée

    OpenBSD OpenSSH

    sshd in OpenSSH before 10.4 allows remote attackers to cause a denial of service (resource consumption from excessive authentication attempts) because MaxAuthTries was mishandled for GSSAPIAuthentication.

  18. CVE-2026-59999 7.5 Élevée

    OpenBSD OpenSSH

    In sshd in OpenSSH before 10.4, DisableForwarding=yes was supposed to take precedence over PermitTunnel=yes, but did not.

  19. CVE-2026-59998 6.5 Moyenne

    OpenBSD OpenSSH

    sshd in OpenSSH before 10.4 has an undocumented security-relevant behavior: GSSAPIStrictAcceptorCheck has no value if the server is in Windows Active Directory.

  20. CVE-2026-59997 5.4 Moyenne

    OpenBSD OpenSSH

    internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.

  21. CVE-2026-59996 5.4 Moyenne

    OpenBSD OpenSSH

    scp in OpenSSH before 10.4 may place a file in the parent directory of an intended directory when the copy occurs between two remote destinations.

  22. CVE-2026-59995 5.4 Moyenne

    OpenBSD OpenSSH

    sftp in OpenSSH before 10.4 does not properly constrain the location of downloaded files when "sftp server:/path ." is used with an attacker-controlled server.

  23. CVE-2026-55655 6.1 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session.

  24. CVE-2026-55654 3.7 Faible

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 9 · Red Hat Hardened Images · Red Hat Update Infrastructure 5

    A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI (Generic Security Service Application Programming Interface) indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service.

  25. CVE-2026-55653 6.5 Moyenne

    Red Hat Enterprise Linux 10 · Red Hat Enterprise Linux 10.0 Extended Update Support · Red Hat Enterprise Linux 8 · Red Hat Enterprise Linux 9

    A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange (DH-GEX) client path. This occurs during FIPS (Federal Information Processing Standards) mode known-group validation when the client processes attacker-controlled DH-GEX group parameters. Successful exploitation leads to client-side process termination, resulting in a Denial of Service (DoS).
